Measurement section 36 for exporting from black and white scan converter 24 and the faultage image that (current) is updated in actual time, measure utilize the 1st up-to-date signature waveform and and heart bat cycle set by the 1st signature waveform continuous print the 2nd signature waveform in, the cardiac measurement value such as length, ejection fraction (EF value) between the area of heart, the volume of heart, 2 measurement points.Then, measurement section 36 makes image displaying part 26 show cardiac measurement value together with the faultage image that (current) is updated in actual time.
Utilize Fig. 2 to specifically describe the present embodiment.Fig. 2 is an example of the image be shown in image displaying part 26.The cardiac measurement value 80 showing the electrocardiographic wave 50 detected by electrocardiographic wave test section 30, the faultage image 70 exported from black and white scan converter 24 and measured by measurement section 36 in image displaying part 26.
Electrocardiographic wave 50 is detected by electrocardiographic wave test section 30, and electrocardiographic wave 50 demonstrates the display tense labelling 52 in the moment (tense) representing actual time (current).The renewal of display tense labelling 52 and electrocardiographic wave 50 side by side on time orientation (right direction) move and be shown.If display tense labelling 52 reaches right-hand member, then show tense labelling 52 and move to left end, be side by side repeatedly shown with the renewal of electrocardiographic wave 50.Electrocardiographic wave after the electrocardiographic wave 50 shown in the left side of display tense labelling 52 is updated.
Demonstrate in image displaying part 26: the R ripple 58 of the R ripple 56 of that detected by signature waveform test section 32, up-to-date for the moment of actual time (current) R ripple 54, and then R ripple 54 and and then R ripple 56.The R ripple detected by signature waveform test section 32 is the one of signature waveform.
R ripple 54 is R ripples up-to-date for the moment of actual time (current), becomes up-to-date R ripple.R ripple 56 is the 2nd new R ripples for the moment of actual time (current).Similarly, R ripple 58 is the 3rd new R ripples for the moment of actual time (current).
The heart claps cycle set portion 34 based on the R ripple as the signature waveform detected by signature waveform test section 32, sets to utilize up-to-date R ripple 54 and be only second to the new heart set by R ripple 56 of R ripple 54 to clap cycle A (R-R cycle).The heart clipped by R ripple 54 and R ripple 56 claps cycle A to be become the heart in 1 cycle clipped by up-to-date signature waveform and the 2nd new signature waveform and claps the cycle.Thus, become the heart the shortest with the difference in the moment of actual time (current) by the heart bat cycle A that R ripple 54 and R ripple 56 clip and clap the cycle.The heart the shortest with the difference in the moment of actual time (current) cycle of clapping also can be called the up-to-date heart and clap the cycle.
Clapping on the suitable electrocardiographic wave of cycle A 50 with the heart, demonstrating electrocardiographic wave labelling 60 at image displaying part 26, being set by heart bat cycle set portion 34 up-to-date heart bat cycle A can be identified.About electrocardiographic wave labelling 60, such as illustrate by the line type (thick line, dotted line etc.) different with electrocardiographic wave 50 clapping on the suitable electrocardiographic wave of cycle A 50 from the heart clipped by R ripple 54 and R ripple 56, or illustrate by the color different with electrocardiographic wave 50 (red, blue etc.) clapping on the suitable electrocardiographic wave of cycle A 50 from the heart.
Faultage image 70 is cross-section images of the heart of subject 10, such as, be apex two chamber picture (A2C).Faultage image 70 is provided with multiple measurement point.In the present embodiment, the measurement point of 9 is set along the inwall of the heart be shown as faultage image.Region 76 is the regions surrounded by multiple measurement point.
Measurement section 36 is measured and is clapped the cardiac measurement value such as length, ejection fraction between the area of the relaxing period of cycle A and Syst, heart, the volume of heart, 2 measurement points by the heart heart clapped set by cycle set portion 34.
Relaxing period refers to after heart contraction diastole, to heart, injects the interval of blood from whole body.Systole refers to the interval that blood is sent to whole body by heart contraction.Relaxing period is the interval after R wavefront, such as, be the interval after R wavefront 500ms to R ripple till 50ms.Systole is the interval have passed through the stipulated time from R after, such as, be the interval after R ripple after 50ms to R ripple till 300ms.R ripple is included in the interval of relaxing period, R wave table show systole start before diastasis.
First, measurement section 36 is measured and is clapped length between the area of the mesodiastolic heart of cycle A, the volume of heart, 2 measurement points by the heart heart clapped set by cycle set portion 34.Measurement section 36 such as measure as the heart clap the moment of the ED R ripple of cycle A, length between the area of heart, the volume of heart, 2 measurement points.Refer to the period that the diastole of heart terminates diastasis.The ED R ripple clapping cycle A as the heart both can be R ripple 54 up-to-date for the moment of actual time (current), also can be the R ripple 56 of and then R ripple 54.In addition, in the present embodiment, because prerequisite measures ejection fraction, thus suppose that the moment at the R ripple 56 of heart bat cycle A carries out the measurement of relaxing period.Measurement section 36 measures the length between the area of the heart in the moment of R ripple 56, the volume of heart, 2 measurement points.Length between the area of the heart of the relaxing period measured by measurement section 36, the volume of heart, 2 measurement points is shown as the cardiac measurement value 80 of image displaying part 26.
Further, measure in the same manner as the measurement that measurement section 36 and the heart clap the relaxing period of cycle A and clap length between the area of the Syst heart of cycle A, the volume of heart, 2 measurement points by the heart heart clapped set by cycle set portion 34.Measurement section 36 is such as measured from the moment of R ripple and be have passed through length between the area of the end-systolic heart after the stipulated time, the volume of heart, 2 measurement points.
End-systole refers to the period that the contraction of heart terminates, be such as the volume of heart become minimum when.All tomograph picture frames that measurement section 36 is clapped in cycle A (the previous heart claps the cycle) for the heart carry out volume computing, determine the tomograph picture frame of the minimum volume of giving heart, determine the end-systolic moment thus.Then, measurement section 36 uses end-systolic tomograph picture frame to measure the length between the area of heart, the volume of heart, 2 measurement points.
Measurement section 36 can measure the length between 2 measurement points being optionally set.In addition, measurement section 36, by combining multiple measurement results of the length between 2 measurement points being freely set, can measure the cardiac measurement such as long axis length or minor axis length value thus.In addition, measurement section 36 can also measure ratio and the L Index value of the long axis length of different section.
In addition, measurement section 36 measures the change of the volume of heart in advance, becomes the time (T1) minimum moment based on the change volume measured from the moment of R ripple to heart of the volume of measured heart.Then, measurement section 36 is measured from the moment of R ripple 56 and be have passed through length between the area of the end-systolic heart after the stipulated time (T1), the volume of heart, 2 measurement points.
At this, the measuring method of the area of heart is described.The area in the region 76 surrounded by multiple measurement point is measured based on the pixel count comprised in region 76.First, the pixel count in measurement section 36 pairs of regions 76 counts.Measurement section 36 grasps every 1mm in advance
2pixel count, area conversion is carried out to the pixel count be counted out in region 76, thus the area of measured zone 76.Such as, if measurement section 36 is in advance by every 1mm
2pixel count grasp as 10 pixels, if the pixel count be then counted out in region 76 is 5000 pixels, such area is scaled 500mm
2.
Secondly, the measuring method of the volume of heart is described.Measurement section 36 uses simpson's method (Simpson) to measure the volume of heart.Simpson's method is following method: on longitudinally, the region 76 surrounded by multiple measurement point is divided into rectangular area, obtain the area of rectangular area, calculate volume for each rectangular area, be added obtained volume by the rectangular area after segmentation, obtain volume thus.
Secondly, the measurement of length method between 2 measurement points is described.First, operator utilizes operating portion 40 to set 2 measurement points within 9 measurement points.At this, suppose to set measurement point 72 and measurement point 74.Distance between set measurement point 72 and measurement point 74 is measured as the length between 2 measurement points by measurement section 36.
Afterwards, measurement section 36 carrys out computing ejection fraction according to the volume of measured ED heart and the volume of end-systolic heart.Ejection fraction is obtained according to the following formula of the volume of heart and the volume of Syst heart that employ relaxing period.
{ formula 1}
Ejection fraction (%)=(Va (volume of ED heart)-Vb (volume of end-systolic heart)/Va × 100
Ejection fraction is utilized the volume of the heart in the moment as ED R ripple 56 and calculates as the minimum volume of end-systolic heart by measurement section 36.Ejection fraction is the evaluation of estimate of the contractile function representing heart.In addition, in measurement section 36, except ejection fraction, the measured value in diastasis and the measured value in end-systole can also be combined and calculate and represent that the heart claps the desired value of the causing circulatory function of cycle A.Such as, measurement section 36 utilizes the difference of the volume of the volume of ED heart and end-systolic heart based on following formula, can measure cardiac output or a cardiac output that the heart claps the blood in cycle A.
{ formula 2}
Cardiac output=heart umber of beats × (Va-Vb)
(formula 3}
A cardiac output=Va-Vb
Secondly, Fig. 3 is utilized to illustrate renewal cardiac measurement value 80.Fig. 3 (a) represents that the heart shown in Fig. 2 claps the form of state.Fig. 3 (b) represents that the heart illustrated from Fig. 3 (a) state of clapping have passed through the form that the heart after the stipulated time claps state.Fig. 3 (c) represents that the heart illustrated from Fig. 3 (b) state of clapping have passed through the form that the heart after the stipulated time claps state.
The display tense labelling 52 in the moment (tense) of the expression actual time (current) that Fig. 3 (a) illustrates above moves and is shown at time orientation (right direction) with the renewal of electrocardiographic wave 50 in the lump.As shown in Fig. 3 (b), when display tense labelling 52 reaches the R ripple 62 as new R ripple, signature waveform test section 32 detects the R ripple 62 as signature waveform.R ripple 62 is R ripples up-to-date for the moment of actual time (current), becomes up-to-date R ripple.R ripple 54 becomes the 2nd new R ripple for the moment of actual time (current).
The heart is clapped cycle set portion 34 and is reset heart bat cycle B (R-R cycle) clipped by the R ripple 54 of up-to-date R ripple 62 and and then R ripple 62.Thus, under the heart bat state that Fig. 3 (b) illustrates, become the up-to-date heart by the heart bat cycle B that R ripple 62 and R ripple 54 clip and clap the cycle.
Then, measurement section 36 is for the faultage image 70 being updated to actual time (current), and the heart measured set by heart bat cycle set portion 34 claps the cardiac measurement value such as length, ejection fraction between area in cycle B, heart, the volume of heart, 2 measurement points.Because it is same that the heart claps the measurement that measurement in the relaxing period of cycle B and systole and the heart clap in the relaxing period of cycle A and systole, so the description thereof will be omitted.The heart measured by measurement section 36 is clapped the length between the area of the relaxing period of cycle B and Syst heart, the volume of heart, 2 measurement points and is overwritten in cardiac measurement value that past measurement goes out as the cardiac measurement value 80 of image displaying part 26 and shows.
Thus, whenever represent actual time (current) moment display tense labelling 52 by new signature waveform time, detects whenever signature waveform test section 32 signature waveform made new advances time, the heart clap cycle set portion 34 set the heart bat cycle.Specifically, the heart is clapped cycle set portion 34 and is set the heart and clap the cycle, and this heart cycle of clapping is the cycle set by the 2nd signature waveform according to the 1st up-to-date signature waveform that newly detects and and then the 1st signature waveform.Thus, when signature waveform test section 32 detects the signature waveform made new advances, the heart is clapped cycle set portion 34 and is upgraded the heart bat cycle, the cycle that the heart can be clapped ensure up-to-date all the time thus.
Then, measurement section 36 measures the cardiac measurement value that the heart that is updated when detecting the signature waveform made new advances at every turn claps length between the area of the relaxing period in cycle and Syst heart, the volume of heart, 2 measurement points, ejection fraction.The heart after image displaying part 26 display is updated claps the relaxing period in cycle and Syst cardiac measurement value 80.
As shown in Fig. 3 (c), when detect the R ripple 62 as signature waveform from signature waveform test section 32 to detecting next R ripple during in, image displaying part 26 continues the cardiac measurement value 80 that the display heart claps the length between the area of the heart in the relaxing period of cycle B and systole, the volume of heart, 2 measurement points.
